Описание тега sequelize-cli
Интерфейс командной строки (CLI) Sequelize поддерживает миграции и сеялки.
The Sequelize Command Line Interface (CLI) supports for migrations and seeders.
With migrations and seeders it's possible to transfer an existing database into another state and vice versa: those state transitions are saved in migration storage and seeder storage accordingly, which describe the way how to get to the new state and how to revert the changes in order to get back to the old state.
